2 Claims. (or. 254-146) This invention relates to a winch and more specifically provides a multi-purpose winch that is simply, easily and quickly adapted for its various uses.

An object of this invention is to provide a winch that is simple in construction, easy to operate, universal in utility, easily adapted to its various uses, well adapted for its intended purposes and relativelyinexpensive to manufacture.

Another object of this invention is to provide a winch together with a supporting structure for raising and low ering a vehicle or other object. V

i A further object of this invention is to provide a winch that may be secured between two objects for urging the objects toward each other and further provided with a pointed stake for anchoring the winch wherein a vehicle or other device may be pulled along a supporting surface.

Another important object of this inventionis to provide a winch having a novel attaching means for the flexible cable wherein the cable may be easily and quickly changed for varying the capacity of the winch.

Other important objects of the present invention include its utility wherein the device may be employed in various fields such as the transportation industry, material handling devices, elevators of various types, emergency equipment, a towing mechanism for pulling vehicles out of mud holes, snow banks orthe like together with other varied uses that a device of this character may be especially useful.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to likeparts throughout, and in which:

Figure 1 is a perspective view showing the winch of the present invention utilized as a car jack;

Figure 2 is a detailed, longitudinal, vertical sectional view taken along the plane of section line 22 of Figure 1;

Figure 3 is a transverse, vertical sectional view taken substantially along section line 3-3 of Figure 2 showing the details of construction of the winch mounting means together with the attachment means for the end of the flexible cable;

Figure 4 is a detailed sectional view taken substantially along section line 4-4 of Figure 2 showing the details of construction of the winch brake;

Figure 5 is a detailed view showing the detachable base plate that may be provided for the vertical winch supporting standard; and

Figure 6 shows the winch in use as a towing device for utilization with a pointed stake or other secure object for towing a vehicle or the like.

Referring now specifically to the drawings, it will be seen that the numeral 10 generally designates the winch of the present invention including generally an inverted 2,779,563 Patented Jan. 29," 1957 U-shaped frame 12 having a pivotal eye member14 secured centrally of the bight portion thereof by suitable peripheral flanges 16 on each side of the bight portion of the frame 12. A transverse brace 18 rigidifies and braces the leg portions of the inverted U-shaped member 12. A shaft 20 extends through the legs of the U-shaped member 12 and is rotatably journalled therein. A pair of cylindrical plates 24 are secured to the shaft 20 adjacent the inner surface of the legs of the U-shaped member 12 thereby forming a drum and limiting the lateral movement of the shaft 20. A flexible cable 26 is coiled around the central portion of the shaft 20 and is attached to a semi-circular member 28 having an inwardly extending end portion 30 that engages an inwardly extending socket 32 in the shaft 20 wherein the cable 26 is easily, quickly and securely attached to the shaft 20 foreasy and quick detachment therefrom. This permits the use of various sizedcables 26 on the shaft 20 for changing the capacity of the winch 10.

A brake drum in the nature of a collar 34 is secured adjacent one end of the shaft 26} exteriorly of the frame 12 and a circular member 36 having spaced adjacent ends 38 is attached to one side of one of the free legs of the U-shaped member 12 and the circular member 36 is provided with tangential handles 40 for clamping the split circular member 36 about the collar 34 thereby forming a brake for stopping rotation of the shaft 20. By urging the handles 40 toward each other, the sections of the circular member 36 that are not secured to the frame 12 are moved toward each other thereby clamping the collar 34. The band or circular member 36 is attached to the frame 12 at a position opposite from the slit formed by the adjacent ends 38.

A ratchet gear 42 is secured to the end of the shaft 20 on the other side of the frame 12 from the collar 34 and a pivotally mounted pawl 44 is positioned on the frame 12 by a pivot pin 46 and the pawl 44 is disposed over the gear 42 wherein the action of gravity will urge the pawl 44 into engagement with the gear 42 thereby permitting rotation of the shaft 20 in one direction wherein the cable 26 may be wound about the shaft 20. The pawl 44 may be gripped by a finger or the like and raised upwardly thereby permitting the cable 26 to be unwound from the shaft 20. A polygonal end portion 48 is formed on the end of the shaft 20 adjacent the ratchet gear 42 for engagement by a suitable handle 50 wherein the shaft 20 may be rotated about its longitudinal axis for winding the cable 26 about the shaft 20. If desirable, suitable tie means may be provided for rotating the shaft 2% thereby winding the cable 26 on p the shaft 20.

Referring now specifically to Figure 3, it will be seen that a rearwardly extending handle 52 is secured to the transverse brace 18 and includes an aperture 54 for positioning over a vertical tubular standard 56 and a rearwardly extending lug 58 is secured to the hight portion of the frame 12 and a depending pivot pin 66 is secured to the rear-most portion of the lug 58 for engagement in the open upper end of the tubular standard 56. The lug 58 and the handle 52 are in vertically spaced parallel relation thereby securely supporting the winch it on the upper end of the tubular standard 56. The tubular standard 556 is provided with a collar 62 adjustable thereon with a screw-threaded setscrew 64 with a handle 66 wherein the collar 62 may be adjusted longitudinally of the tubular member 56. The tubular member 56 is provided with a plurality of sections 68 and 70 that are telescopically adjusted and provided with a suitable collar 72 with a locking means 74 for securing the tubular member 56 in adjustedposition. The lower end of the lowermost tubular member 70 is provided with a base 76 which may be provided with an upstanding socket 78 for slidably receiving the lower end of the lowermost tubular member 70 wherein the base 76 is detachable therefrom. The collar 72 is provided with a pivot U-bolt 80 with a flexible chain 32 secured thereto for a purpose described hereinafter. The outer or free end of the cable 26 is provided with a hook member 34 also for a purpose described hereinafter.

In operation, the tubular standard 56 is assembled of the base 76 and the frame 12 is positioned on the upper end of the tubular standard 56 by positioning the aperture 54 and the handle 52 over the upper end of the tubular member 56 with pin 60 inserted therein. The handle 52 will-engage the upper end of the collar 62 wherein the frame 12 will be pivotally mounted on the upper end of the tubular standard 56. The cable 26 may be unwound from the shaft 20 so that the hook 84 will engage under the bumper 86 of'a vehicle lid. The shaft 20 may then be rotated by the handle 50 or any other suitable means thereby winding the cable 26 about the shaft 20 and raising the vehicle 80 from the supportingsurface. The winch in this position forms a very efiicient and easily actuated bumper jack for a vehicle 38 and the device may be easily and quickly separated for storage in a relatively small space. When the hook 84 is not in use, it may be engaged with the cross brace 18 wherein the cable 26 will be retained in a taut condition and wound tightly about the shaft 2%. if it is desired to pull the vehicle 83 a metallic rod 90 may be positioned in the ground forwardly of the vehicle 88 and a suitable chain 92 connected to the cable 26 and the eye 14 may also be connected to a chain 94 that is secured around the bumper 36 or any other part of the vehicle 83 wherein the cable 26 may be wound above Further, it will be seen that the winch 10 of the present i invention may be utilized in any manner between any objects either stationary or movable for moving the objects toward each other or moving one of the objects lents may be resorted to, falling within the scope of the appended claims.
